It produces accurate, smooth bores in a wide range of workpiece materials where tight dimensional tolerances are required. The reamer measures 0.3750 inches in diameter with an overall length of 3.5 inches and a flute length of 1.25 inches. Constructed from solid carbide in a bright uncoated finish, the 300-3750 offers rigidity and wear resistance suited to both CNC and manual machine tool setups. Six straight flutes with a right-hand cut deliver clean material removal while maintaining the specified diameter tolerance.\u003c\/p\u003e\u003cp\u003eThis chucking reamer fits standard drill press, lathe, or machining center applications where a straight-shank tool is required. The straight-cylindrical shank seats directly in a drill chuck or collet. Typical use cases include finishing pre-drilled or bored holes to final size in ferrous and non-ferrous metals, plastics, and other machinable materials. Its Series 300D geometry is intended for general-purpose production and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0005 inches ensures consistent, close-tolerance hole finishing\u003c\/li\u003e\n\u003cli\u003eSix straight flutes with right-hand cut for smooth bore finish\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting without adapters\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup in standard machine configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a standard drill chuck or collet capable of accepting a straight-cylindrical shank tool at 0.3750 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the straight shank firmly in a properly sized collet or drill chuck before use, and verify runout with a dial indicator before cutting. Always bring the spindle to a full stop before tool changes. Follow applicable shop safety standards and machine manufacturer guidelines for cutting speed and feed rate selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 300D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-3750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729141924146,"sku":"300-3750","price":108.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_1d0b4b52-c140-4828-81c5-bd65bf816640.jpg?v=1788700750","url":"https:\/\/voomisupply.com\/products\/osg-300-3750-chucking-reamer-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
